Year 3 and 4 have been using learnt skills to control a model aeroplane using sequences
They first had to follow instructions to build a model using Lego WeDo with a tilt sensor and a motor.
They then used sequences to start up the motor after a count down.
They also used used sequences for messaging.
The motor does not start until the aeroplane is tilted. Messages tell you when to fly and when to land!
